in zeoserver.log have:

2016-05-25t09:58:17 (22099) created pid file '/opt/plone-4.2/zeocluster/var/zeoserver/zeoserver.pid'  2016-05-25t09:58:17 (22099) opening storage '1' using filestorage  2016-05-25t09:59:27 (22099) removed pid file '/opt/plone-4.2/zeocluster/var/zeoserver/zeoserver.pid'

all tries "google" references fresh migration. in case production server. there no migrations, no updates, nothing. 14 days ago had complete server restart hoster side - no problem. zeoserver started without problems. today: - bin/plonectl stop - allright. no problems or errors. - bin/zeoserver start - "valueerror: non-zero version length. versions aren't supported." don't understand problems root. can't solve this.

please help..

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
